WIRE-BARBING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 254,767, dated March 7,1882. Application filed October 31, 1881. (No model.)

To all whom it may concern Be it known that I, JAMES J. HATHAWAY, ofBeaver Falls, in the county of Beaver and State of Pennsylvania, haveinvented a new and useful Improvement in WireBarbin g Machines; and I dohereby declare the following to he afull, clear, and exact descriptionthereof.

My invention relates to those machines in which two or more strands ofwire are twisted I0 and furnished with double barbs. This operationnecessitates the use of four spools of wire, one for each strand-wireand one for each barb-wire.

In the machines heretofore most generally in use for this purpose thebarb-wires were fed in laterally, while the strand-wires came inlongitudinally ofthe machine. Such construction required the use ofseparate feeding mechanism'for each barbwire, and was compara- 2o tivelyslow, intricate, and expensive.

In my improved machine the four spools are arranged at the middle andrear end of the machine and the four wiresrun longitudinally thereof.The strand wires extend through grooves in a rod or core in the centerof the rotating twisting-spindle, and the barb-wires are led in throughcurved guides in the rotating head, which cause them, when projectedforward, to pass between the strand-wires and 0 to cross each other inthe path of two laterally-reciprocating bending-slides mounted inalongitudinally reciprocating frame, which, as the strandwires aretwisting, bend the barbs around them. The barbs are then sev- 5 eredfrom the coil by knives attached to the bendingslides, after which theyare drawn out of the machine by the progressive movement of thestrand-wires.

To enable others skilled in the art to make and use my invention, I willnow describe it by reference to the accompanying drawings, (in foursheets,) in which Figure 1, Sheet 1, is a side elevation of my improvedmachine as it appears in operation, 5 except that the spinner-frame 2 isbroken at the frontend and turned a quarter-way around, so as not toconceal the wires. As used in the machine the spin ner-frame2 stands atright angles to the arms 5. Fig. 2 is alongitudinal section of theforward end of the spinner and its journal, and shows the properposition of the arms 5 to the spinner. Fig. 3 is: a verticalcross-section on the line y 3/, Fig. 1. Fig.

Like figures of reference indicate like parts in each.

The machine has a suitable frame, 1, upon which all of its parts aremounted. It has an open spinner or frame, 2, provided with journals 4,which turn in suitable bearings, 3. At the rear end it has a shaft, 61,upon which is 5 a pulley, 62. Power to operate the machine is applied toit by means of the belt 63 and pulley 62.

rear end to the bar 72.

The spools are four in number, 64 65 being the strand-wire spools and 66and 67 the barb- Wire spools. One of the strand-wire spools, 64, isplaced on a vertical spindle, 68,0n a looselypivoted arm or hanger, 69.The forward end is pivoted by a collar to a pin, 70, in the frontjournal, 4, of the spinner 2 and the rear end by a pin, 71, to across-bar, 72, extending between the two arms 2 of the spinner. Thisspool, by reason of the loosely-pivoted hanger 69, remains always in avertical position. The otherstrand-spool, ,65,is placed in a verticalposition on a bracket, 73, at the rear of the machine,and the wire a isled from it through the shaft 61, which is hollow, up overthefriction-wheel 74 on one arm of the spinner, and thence forward tothe point where it joins the wire from spool 64. The spools 66 67, forthe barb-wires, are placed on a shaft or rod, 75, extendinglongitudinally in the spinner from the The wires b b are led overfriction-wheels 76 77 and thence forward.

At the side of the machine is a shaft, 19, which receives'its power fromthe shaft 61 by means of the gear-wheels 78 79. This shaft 19 suppliesthe power to reciprocate the head 11 has a reciprocating motion given toit and to the spindle by means of the following mechanism:-

Journaled in the frame of the machine is a shaft, 13, Fig. 3, which isprovided with a central arm, 14, pivoted to a connecting-rod, 15, saidrod in turn being pivoted toalug, 16, on the under side of the box 12,in which the head 11 rotates.

The power to oscillate the shaft 13 is communicated to it by means of acam, 17, having an eccentric groove, 13, on the side, shaft 19, and'anarm, 20, extending up from the end of the shaft 13, having a pin, 21,which enters the eccentric groove 18. The operation of the cam upon theshaft is to give it an oscillation in its bearing, which oscillation istransmitted to the bearing 12 and causes it and the rotating head 11 andspindle 7 to reciprocate, the spindle 7 moving back and forth in thehollow rotating head 6, from which it receives its rotation. The head 11is sustained and guided by twolugs or carriers, 22, one on each side ofthe bearing 12 which slide on ways 23, formed on the frame of themachine.

Secured by bolts 88 through the overlapping plates or cleats 89 to thebearing 12 in front of the rotating head 11, and reciprocating with it,is a frame, 24, which extends laterally across the machine, and in whichare mounted the bending-slides 25. These slides are secured in suitableretaining-recesses, and are forced inward to operate upon the barbwireby means of stationary cams 10, mounted at each side of the machine,which cams bear upon friction-rollers 26, placed in the ends of theslides 25 ,and cause them to be projected inward at the forward motionof the reciprocating head, during which motion the barbing operation isperformed, so as to do their work of bending the barbs upon thestrand-wires and severing them from the barb-wires. The slides arethrown back during the retraction of the head by the operation of aspiral spring, 27, upon the lower ends of two arms, 28, pivoted totheframes, the upper ends, 29, of which bear outwardly against plates orshoulder 30, fastened by bolts 80 to the slides. The slides 25 areremovable by taking off the upper retaming-plates, 81, which arefastened by bolts 82 to the frame 24.

Inside of the rotating spindle 7is a core-rod of metal, 31, which is ofsuch size as to fit snugly in the bore of the hollow spindle, and issecured therein by set-screws 60, Fig. 9, placed in the slots 9 in thehead 6 and bearing on the rod through a collar,59,on its rear end. Thiscore-rod is provided with two grooves,32, one on each side, which extendfrom end to end of the rod, and near the forward part each makes athree-quarter turn of the rod. The strand-wires a are fed through thesegrooves, being entered at the rear end of the spindle and passed out atthe front, the purpose of the core-rod being to hold them apart duringtheir forward feed until after the barb-wires b are passed between them,when, being freed from the core-rod 31, which separated them, they willtwist beyond the rotating head 11. The barb-wires b are led forwardthrough hollow guides 33, extending along the outer sides of the heads 6and 11. The guides in the head 11 are curved inward at their forwardends, as at 34, which causes the two barb-wires passing through them tobe projected out toward the other side of the machine and to cross eachotherjust in front of the outer end of the core-rod,and just between thetwo strand-wires as they leave the corerod. In the end of the core-rodand opposite to the delivery-openings of the curved guides are twotapered grooves, 35, Fig. 6, so, arranged that when the barbwires leavethe curved guides they enter and pass out through the correspondinggrooves in the end of the core-rod.

The spindle 7 is secured to the head 11, so as to be reciprocatedthereby, by means of the key 83 and by the ends of the curved. guides34, which, curving inward, terminate in recesses 84, Fig. 7, in the endof the spindle. In the working machine these parts are so. compactly puttogether as to move practically as one piece.

The inner ends of the bending-slides 25 are grooved or recessed, as at36, the bottom of the recess curving and extending backward from theupperto the lower side, as shown from I GO 37 to 38. Back of thisrecessed end there is a rectangular recess, 39, extending in from thelower side, 38, to a depth equal to the width of the slide, or nearlyso, there being an enlargement, 40, of the slide opposite to the re ces39, to permit it to be made. At the back side of the rectangular recessa knife or shear,

41, is bolted, with its shearing-edge projecting knives passing over themouth of the curved guide sever the barb c from the barb-wires b at theclose of the barbing operation by a diagonal cut, so as to leave the endof the barb sharp and pointed. Then the slides are in place the lowerone is inverted, so as to bring its recesses opposite to those of theupper slide in their operation on' the barb-wires, as

shown in Figs. 3 and 9.

The barb-wires are fed forward during the forward motion of the machineby the following devices: 7

At each side of the head 6, and fastened thereto by a screw, 85, is arectangular frame,

42, through and across which the barb-wires pass.

At one end of the frame is a stationary serrated jaw, 43, whichextendsalong one side of the wire. On the other side of the wire, and inthe opposite end of the frame, is a pivoted spring-dog, 44, having aserrated biting-edge, said dog being pivoted at such an angle that thewire is free to be drawn through it in a forward direction and cannotpass in a backward direction, because then it is engaged by the dog andis clamped between it and the stationary jaw. Whenthereciprocating-head11 is retracted its tendency is to push back. thebarb-.wires, which causes the locking-dogs to bite upon them and holdthem stationary, while the head 11 slips back over them and causes theirends to be projected beyond the ends of the curved guides 34. Thisprojection is equal to the desired length of the barb.

The forward or nnslotted part of the head 6 is tapped, as at 86, infront of the slots 9, and gage-screws 87 are screwed into the holes 86and extend back into the slots 9 in front of the lugs S. The purpose ofthese screws is to gage the length of the slots 9 to the length of themovement of the head 11 and spindle 7.

The projected ends of the barb-wires, after passing between thestrand-wires, encounter the ends of the approaching bending-slides25,and, entering the grooves 36, are bent thereby around the strand-wires,which meanwhile are twisting between the slides. The further advance ofthe slides 25 completes the coiling of the barbs, causing the free endsto pass out of the grooves 36 into the rectangular recesses 39, and, bythe passage of the knives 41 over the end of the curved guides 34,severing the barb c from the barb wires 1) by a diagonal cut.

At this instant the slides pass ontothe straight part 45 of thestationary cams 10 and the applied barbs c are in the position shown inFig. 9, with their points extending at right angles into the recesses 39and between the adjacent sides 38 of the bending-slides. The straightpart 45 of the cams 10 permits the slides to remain at rest an instantat the end of the forward stroke of the head 11, and this is to givetime for the withdrawal of the barbs from between the bending-slidesbefore the latter are retracted. It'the slides were retracted instantly,the barbs would be partially uncoiled by them, because two oppositepoints, one on each barb, extend into'the rectangular recesses 39 andwould be drawn back by the sides of the same when the slides wereretracted. As it is, the barbs have been drawn out'clear of the slideswhen they begin their retrogres ion. a

The finished wire cl passes over the wheel 46 down to the reel 47, uponwhich it is wound. The wheel 46 is driven by a bevel-pinion, 48, on theend of the side shaft, 19, meshing into a large bevel-gear, 49, on theend of the shaft 50 of the wheel 46. The reel 47 is driven by the belt51 from a pulley, 52, 01 the side shift, 19, extending to a pulley, 53,on a countershaft, 54, which, by means of. beveled-gear wheels 55,drives the reel-shaft 56.

The shafts 50 and 56 arejournaled in a frame, 90, bolted to the frontend of the machine.

The draft of the wheel 46 and reel47 upon the strand-Wiresconstitutesthepowerwhiehdraws the strand-wires a through the machine. This draftbeing constant, the strand-wires have a constant feed. On the otherhand, the feetlbt' the barb-wires is intermittent, being made on thebackward movement of the head 11 only. Each forward movement of the headdraws enough wire off of the barb-wire spools to form one pair of barbs.A

The operation of my improved machine is as follows: The ends of thestrand-wires a are by hand passed through the hole 91 in the frontjournal, 4,ot' the spinner2, andonepassed through each groove 32 32 ofthe core-rod 31, and then they are both drawn over the wheel 46 andfastened to the reel 47. The ends of the barb-wires b are passed overthe frictionwheels 76 77, carried forward, and one passed through eachof the holes 92 92 in the front journal, 4, of the spinner and throughthe guides 33 34. Power is then ap lied to the machine. Imagine it inthe position shown by the dottedlincs in Fig.5, Sheet 2. In thisposition the operation of applying and severing the barbs has beencompleted. The position of the bending-slides immediately after thesevering of the barbs is shown in Fig. 13, Sheet 4. 'During the entireoperation otithe machine the strand-wires are being drawn through themachine by the operation of the power-d riven reel 47, and are beingconstantly twisted by the rotation of the head 11. ,The head 11 thenbegins to move backward. This causes the spring-clogs 44 to releasetheir hold on the barb-wires b, and the latter remain stationary whilethe head 11 goes back.- The result is that the ends of the barb wiresare projected from the curved guides 34 across each other and bet weenthe strand-wires to a length equal to the backward movement of the head11, which length is that required for the applied barbs. During thefirst part of the backward movement, the bending-slides, being on thestraight. surfaces 45 of the cams 10, do not depart from the positionshown in Fig. 13. This allows ample time for the barbs last applied tobe drawn front the bending-slides before they change position. When thehead 11 is partially retracted on the incline 93 of the catns thebending-slides and barb-wires are in the position shown in Fig. 10,Sheet 4. When fully retracted they are in the position shown in Fig. 11.When beginning to advance they are in the position shown in Fig. 12, andwhen at the extreme forward limit of the movement they are in theposition shown in Fig. 13. The head 11 revolves in the direction of thearrows, and the ends of the barb-wires I), being held by the grooves 36of the non-rotating slides 25, are guided thereby, while the twisting ofthe strand-wires winds them up upon the strand-wires. At the instantthis is accomplished the abrupt ends 94 of the inclines of the cams 10,acting on the slides, project them inward to the position shown in Fig.13, bringing the recesses 39 opposite each other, cutting off the barbs,and drawing the forward ends, 0 of the barbs out of the grooves 36.Then, the slides being on the straight surfaces of the cams 10, and thepoints of the barbs ltlIOjGCblllg into the recesses 39, and the clearspaces between the adjacent sides of the slides,

the advance of the strand-wires draws the applied barb safely out fromthe bending devices. In case any of the Wires give out, the machine isstopped, a new spool put in, and the end of the wire drawn through andspliced by twisting it around the other wires beyond the outer end ofthe head 11.

Many of the devices in the machine just de scribed maybe varied by theskilled constructor by the use of equivalent means well known inmechanics, and it will therefore be unnecessary for me to indicate them.

The main feature of my invention is applying the barbs to the twistingstrand-wires by means of laterally-moving bending. and severing devices,and also of the construction of those devices,which permits the saferemoval of the applied barbs from the bending mechanism. I The machineis automatic in its operation, and requires only to have the spoolsrenewed when empty. It can be used with one or with three or morestraudwires without material change. it may also be used to apply asingle barb to the strand wire or wires. When but one strand-wire is ued the core-rod is not needed, and when but one barb-wire is used onlythe opposite bending-slide is needed.

The advantages of my improvement are great rapidity and certainty ofoperation, the perfect application of the barbs to the strandwires, andthe simplicity of the machine.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of a reciprocating rotatin g head, a pair'oflaterally-reciprocating bending-slides, and a knife or knives movingwith the slides, substantially as and for the purposes described.

A pair of laterall y-reciprocatin g bendingslides, forked or grooved inthe ends for receiving the ends of the barb-wire, and each provided witha recess for allowing the withdrawal of the finished barb, and a knifefor cutting off the barbs at the end of the stroke, substantially as andfor the purposes described.

3. A pair of laterally-reciprocatingbendingslides, in combination withstationary cams, which force them inward to bend the barbs, the saidcams having straight surfaces at their outer ends, which permit theslides to have a short stop while the applied barb is being withdrawn,substantially as and for the purposes described.

4. The combination of a rotating reciprocatin g head having a hollowspindle and curved barb-wire guides with a pair oflaterally-reciprocating bending and severing slides, substantially asand for the purposes described.

5. Abending-slide forked or grooved in the end, and provided with alateral recess back of the groove, and a knife or shear in the rear sideof the recess and projecting into it, substantially as and for thepurposes described.

6. The rotating barbing-head having a 1101- low spindle andinwardly-curved barb-wire guides, in combination with acore-rod havinglateral grooves in its end, substantially as and for the purposesdescribed.

7. The reciprocating barbing-head having a curved guide or guidesthrough which the barb-wire is fed, in combination with devices whichhold the barb wire or wires stationary, so that the head shall slip overthem during its backward movement, substantially as and for the purposesdescribed.

8. The reciprocating barbinghead having a barb-wire guide or guides, incombination with the non-reciprocating spring-dog, which permits thebarb-wire to be drawn forward at the forward movement of the head andprevents its moving back at the backward movement of the head,substantially as and for the purposes described.

In witness whereof I have hereunto set my hand this 4th day of October,A. D. 1881.
